I understand the hatred of the MC towards his former friends/childhood friends and family.
the officer, hero and the childhood friend the saint doesn't deserve their gifts/skills if the MC has the skill known as skill taker, he can strip the gifts/skills from them since he doesn't have it, I hope he make good on the MC promise to put them through a living hell and make them suffer. this is much like (Nyanja and Pomeko- even if you say you believe me now, it’s too late) and (The Girls Who Traumatized Me Keeps Glancing at Me, but Alas, It’s Too Late) soon a friendship, trust and family trust is destroyed there is no hope in repairing the damage that is done
